This article focuses on "how to solve the @ Valid check invalid, BindingResult did not get the error", interested friends may wish to take a look. The method introduced in this paper is simple, fast and practical. Now let the editor take you to learn "how to solve the @ Valid check invalid, BindingResult did not get the error" bar!

Catalogue

@ Valid check invalidation

Problem description

Solution process

Use bindingResult for parameter verification

In the control class

Entity class OrderForm

@ Valid check failure problem description

Use @ Valid to verify the attribute stuTele in the entity class

Import javax.validation.constraints.Size;...@Size (min = 11 ~ max = 11 ~ ~ message = "Please enter 11-digit mobile phone number") private String stuTele

In Controller, check the property value of the student object passed in with the @ Valid annotation

Public String updateStuMsg (@ Valid Student student, BindingResult bindingResult, Model model, HttpSession httpSession) {.}

After passing in the error parameter, it is found that the error recorded in bindingResult is 0, which means the check is invalid.

Solution process

Check for introduced dependencies:

Org.hibernate hibernate-validator 7.0.1.Final javax.validation validation-api 2.0.1.Final

After switching the version of hibernate-validator to 5.4.1.Final, it is found that the verification is normal.

So it is positioned as a dependent version problem.

My springboot version is 2.5.1, and the check takes effect after replacing the dependency with the following

Org.springframework.boot spring-boot-starter-validation

Go into the spring-boot-starter-validation and look at its dependencies, including one of these

Org.hibernate.validator hibernate-validator 6.2.0.Final compile

So you can also use this version directly when you modify dependencies externally.

The dependency of validation-api does not need to be retained.

So how do you use the latest version of 7.0.1.Final? That's what the official document says.

Jakarta Bean Validation defines integration points with CDI (context and dependency injection for Jakarta EE). If your application runs in an environment that does not provide such out-of-the-box integration, you can use the Hibernate Validator CDI portable extension by adding the following Maven dependencies to your POM:

Example 1.3:Hibernate Validator CDI Portable extension Maven dependency

Org.hibernate.validator hibernate-validator-cdi 7.0.1.Final

Note that applications running on Java EE application servers usually do not need to add this dependency.

Then, you just need to replace all the previous dependencies with this one, and that's fine.

Org.hibernate.validator hibernate-validator-cdi 7.0.1.Final uses bindingResult for parameter verification in the control class @ RequestMapping ("/ create") public void create (@ Valid OrderForm orderForm, BindingResult bindingResult) {if (bindingResult.hasErrors ()) {log.error ("[incorrect order creation parameters], orderForm= {}", orderForm) / / bindingResult.getFieldError (). GetDefaultMessage () can get the error prompt throw new OrderException (ResultEnums.PARAM_ERROR.getCode (), bindingResult.getFieldError (). GetDefaultMessage ());} entity class OrderForm@Datapublic class OrderForm {@ NotEmpty (message = "required name") private String name;// buyer name @ NotEmpty (message = "Mobile number required") private String phone / / buyer's mobile phone number @ NotEmpty (message = "required address") private String address;// buyer address @ NotEmpty (message = "openid required") private String openid;// buyer Wechat @ NotEmpty (message = "Shopping cart cannot be empty") private String items / / Shopping cart} at this point, I believe you have a better understanding of "how to solve the @ Valid check invalid, BindingResult did not get the error", you might as well do it in practice!
